This bug is fixed now in the CVS version of Xr.

It turns out that the clip region was being translated so that its
bounding box coincided with the origin.

The example you gave before should work now. Let me know if you see
any more problems.

And do note that clipping only works for XrStroke and XrFill
currently, (eg. images and text will not yet be clipped). Also, the
clipping code is not optimized at all so don't be surprised if the
performance is underwhelming.
